It really depends on the skill level of the chiro.
My daughter's interests involve a great deal of stress on the ankles, wrists and elbows and he always sets them straight. I asked him directly, just last month, if they don't teach those 'adjusting skills' at chiro college, where would one learn>
He told me he always goes to continuing ed courses put on by specialists who do sports medicine, where these additional extremities are taught.
So if your guy hasn't been to these courses, he's just usin' ya as a guinea pig, sorry.
I do recommend that you continued to be treated by Chiro PLUS have a full medical evaluation. Also Physical Therapy with someone who has been certified as ART (Active Release Therapy.)
